Introduction to Biomechanics in Strength and Resistance Training

When it comes to achieving excellent results in strength and resistance training, understanding the precise mechanics of your body becomes an absolute necessity. Biomechanics, a field that combines the principles of physics with human motion, provides the foundation for such an understanding.

Biomechanics in strength training isn't just about lifting weights or hitting the gym regularly; it's about how well you understand your body's limits, movement patterns, joint mechanics, muscle functions, and how to employ these to maximise workout results. This in-depth understanding also minimises the risk of potential injuries.


In the world of bodybuilding, biomechanics has a definitive role to play. It aids athletes in maintaining appropriate joint alignment and movement patterns. This not only helps in achieving precise muscle contractions but also plays a pivotal part in targeting specific muscle fibers leading to desired aesthetic results in bodybuilding. A perfect blend of these mechanical principles enables bodybuilders and athletes to train smarter, not harder, contributing to their overall performance.


Understanding Biomechanics in Strength and Resistance Training

True fitness goes way beyond the underlying "no pain, no gain" trope - at Movement Method we understand it's about exercising the right way. Lifting heavy weights without understanding the proper mechanics can lead to ineffective training or worse, sustained injuries.


At its core, biomechanics provides an in-depth comprehension of how the body responds to various forces applied during resistance training, including the effects on joints, connective tissues, and muscles. Essentially, it guides on executing proper joint alignment, movement patterns, and angles to attain precise muscle contractions.


Let's take the bench press exercise as an example. Understanding biomechanics will enable you to grasp how the change in an angle, like moving from a flat bench press to an incline bench press, can shift the muscle focus from the mid-pectoral muscles (sternal head) to the upper pectoral muscles (clavicular head). Such knowledge can help you customise your workout to target specific muscle groups as per your goals.


When it comes to resistance training, understanding biomechanics allows you to appreciate how different angles can affect muscle activation. For instance, when performing bicep curls, changing from an overhand (pronated) grip to an underhand (supinated) grip can result in variations in bicep and forearm muscle activation. This understanding further helps in muscle-specific targeting, a critical aspect in bodybuilding and athletic performance enhancement.


Stay put, let's proceed to our next section, which explains how understanding biomechanics plays an integral role in preventing injuries during workouts.

Biomechanics and Injury Prevention at Movement Method

One of the crucial aspects of incorporating biomechanics in strength and resistance training is injury prevention. By understanding the mechanics of movement, trainers can minimise potential risks and create a workout regimen that promotes safe and effective training.


Importance of Proper Movement Patterns and Angles

Biomechanics helps identify optimal movement patterns and angles during exercises to reduce the stress placed on joints and connective tissues. This is particularly important when working with heavy weights or performing complex movements. By maintaining proper alignment and utilising correct angles, you can minimise the risk of joint strain, tendon overuse, and other common workout injuries.

Consider the squat exercise, a fundamental movement in strength training. Proper biomechanics emphasise maintaining an upright torso, tracking the knees in line with the toes, and engaging the glutes throughout the movement. Failure to adhere to these principles can lead to poor movement mechanics, increasing the risk of knee instability, lower back pain, or hip joint impingement.


Preventing Overstress on Joints

Biomechanics also plays a vital role in preventing joint stress and overuse injuries. By understanding how forces are distributed through the body during exercises, trainers can modify techniques and exercise selection to minimise joint load.


For example, when performing the deadlift exercise, proper biomechanics involves initiating the movement from the hips, keeping the back flat, and engaging the posterior chain muscles. By employing this technique and understanding the distribution of forces, particularly on the lumbar spine, you can reduce the risk of lower back injuries that commonly occur during deadlifts.


Avoiding Recruitment of Unwanted Muscle Tissue

Another advantage of applying biomechanics in training is the ability to target specific muscle groups while minimising the recruitment of unwanted muscle tissue. This is particularly relevant in bodybuilding, where sculpting and shaping specific muscle groups are key objectives.


Understanding muscle anatomy, joint mechanics, and the principles of biomechanics allows trainers to modify exercises and angles to emphasise muscle activation in desired areas. For example, a bodybuilder who aims to develop their hamstrings may incorporate Romanian deadlifts into their training routine to focus on the posterior chain without excessive activation of the lower back or quadriceps.


With the right knowledge of biomechanical principles, trainers can optimise exercises, adjust angles, and create personalised training programs tailored to individual goals and muscle development. By doing so, they can minimise the risk of injury while maximising the overall effectiveness of the workout routine.

Now that we have explored the importance of biomechanics in injury prevention during strength and resistance training, let's move on to the next section and dive deeper into its practical applications.


Injury-induced muscle imbalances and movement compensations can greatly affect an individual's performance and training outcomes. By implementing biomechanical analysis and assessment, rehab specialists can identify movement dysfunctions and develop targeted exercises to correct imbalances and promote efficient movement patterns, leading to enhanced recovery and reduced risk of reinjury. These strategies validate the importance of biomechanics not only in injury prevention but also in rehabilitation and returning individuals to their desired level of activity.


Application and Examples of Biomechanics in Training at Movement Method

Biomechanics is not just a theoretical concept; it has direct practical applications in various exercises and training modalities. Let's delve into some examples of how biomechanics can be applied to optimise your training and achieve optimal results.


Biomechanics in Squats

The squat exercise is a compound movement that engages multiple muscle groups, including the quadriceps, hamstrings, glutes, and core. Understanding biomechanics can help you perform squats with proper form and activate the targeted muscles effectively.

  • Squat Depth: Biomechanical analysis reveals that achieving a proper squat depth, ideally below parallel, maximises muscle activation of the lower body. This depth ensures optimal recruitment of the glutes and hamstrings, leading to better muscle development.

  • Foot Placement: Biomechanics also guides us in determining proper foot placement during squats. A shoulder-width stance with feet slightly turned outward helps maintain stability and allows the knees to track in line with the toes, reducing undue stress on the joints.

  • Bar Placement: The placement of the bar on your back during the squat affects the distribution of forces. High-bar squats (bar resting on traps) emphasise quadriceps activation, while low-bar squats (bar resting on rear deltoids) engage the glutes and hamstrings to a greater extent.

Biomechanics in Triceps Workouts

Another area where biomechanics plays a significant role is in targeting specific muscle groups during resistance exercises, such as triceps workouts. Understanding the biomechanics of the triceps can help you optimise exercises to maximise muscle activation.

  • Cable Pushdowns: Proper execution of cable pushdowns involves keeping the elbows close to the body, maintaining a neutral wrist position, and focusing on the downward movement. By incorporating biomechanics principles, you can emphasise triceps activation while minimising the involvement of other muscle groups.

  • Close-Grip Bench Press: Biomechanical analysis of the close-grip bench press demonstrates that a narrower grip allows for greater triceps involvement. Keeping the elbows close to the body and performing the movement through a controlled range of motion can further optimise triceps activation.

Understanding the biomechanics of specific exercises enables you to customise your training based on your goals, whether it's building muscle, improving strength, or increasing power. By incorporating proper movement patterns, angles, and muscle-specific targeting, you can optimise your workouts and achieve the desired results.

Fact: Biomechanical analysis has shown that employing proper form and techniques can enhance muscle activation and reduce stress on joints by up to 30%.

Basic Biomechanics Principles for Resistance Training

To fully understand and apply biomechanics in strength and resistance training, it is important to grasp the fundamental principles that govern the mechanics of human movement. Let's explore some of these key principles:


1. Kinetics and Kinematics

Biomechanics can be divided into two main branches: kinetics and kinematics.

Kinetics deals with the study of forces and their impact on movement. This involves understanding concepts such as forces applied to the body, moments of force (torque), and the resulting joint reactions. Kinetics provides insights into the forces produced by muscles during resistance training and how these forces affect joint loading and movement coordination.

Kinematics, on the other hand, focuses on motion without considering the forces involved. This branch of biomechanics examines the spatial and temporal aspects of movement, including joint angles, joint range of motion, velocity, and acceleration. Kinematics helps determine optimal movement patterns to maximise muscle activation and performance.


2. Mechanical Concepts

Several fundamental mechanical concepts play a crucial role in understanding biomechanics in resistance training. Let's briefly explore some of them:

  • Force: Force is a key factor in resistance training. It is the push or pull that can cause a change in an object's motion or shape. In strength training, the force generated by muscles determines the ability to lift or move weights.

  • Leverage and Moments of Force: Leverage refers to the mechanical advantage gained by changing the position of the body or an external resistance to increase force production or alter the difficulty of an exercise. Understanding leverage allows individuals to optimise exercise techniques and target specific muscle groups effectively.

  • Velocity and Acceleration: Velocity is the rate at which an object changes its position, while acceleration is the rate at which an object changes its velocity. In resistance training, controlling velocity and acceleration can significantly impact the intensity and effectiveness of exercises.

  • Inertia: Inertia is the tendency of an object to resist changes in its state of motion. It is particularly relevant in resistance training when energy is transferred from one muscle to another.

  • Momentum: Momentum is the product of an object's mass and its velocity. In the context of resistance training, maintaining control over momentum is essential to prevent injury and ensure effective exercise execution.

Understanding these concepts helps trainers optimise exercise selection, form, and technique to achieve their desired training outcomes.


3. Tools and Techniques for Biomechanical Analysis

To gain deeper insights into the mechanics of human movement during resistance training, researchers and trainers employ a variety of tools and techniques:

  • Motion Capture Systems: These systems use markers placed on the body to track motion and create 3D models, helping observe and analyse movement patterns accurately.

  • Electromyography (EMG): EMG measures electrical activity in muscles during exercise. It provides valuable information about muscle activation and recruitment patterns.

  • Force Platforms: Force platforms assess ground reaction forces generated during exercise, helping understand how forces are distributed through the body.

  • Accelerometers: Accelerometers measure changes in acceleration and allow for the quantification of movement patterns, providing insights into technique and efficiency.

By utilising these tools and techniques, trainers and researchers can refine exercise technique, optimise training programs, and enhance performance.
